Costeño Beach Surf Forecast and Surf Report

G’day, Rusty here. Look, we’ve got a bit of a mixed bag on the cards for Costeño Beach over the next couple of weeks. The water temp is sittin’ around 81.5°, which is pretty much what you’d expect for this time of year – no weird anomalies to worry about. The first few days are a tough watch, with the swell energy weak and the winds mostly messin’ things up, but there’s a glimmer of something decent if you’re patient.

Right from the get-go, Sunday the 26th is a write-off. You’ve got a weak 4.3ft swell from the NE, but it’s short period (7 seconds) and the wind is cross-on at 6 mph. The combined energy is a measly 164, so it’s just not worth paddlin’ out. Monday the 27th ain’t much better – still small, with a 4.3ft swell and the wind onshore in the mornin’, switchin’ to a light cross in the arvo. Scores are rock bottom. Tuesday the 28th and Wednesday the 29th stay in the doldrums: small swell, poor winds, and the energy barely crackin’ 150-350. The surf is flat or just messy.

Thursday the 30th sees the swell pick up a touch to 5.9ft from the NE, period stretchin’ to 8 seconds, and the energy bumps up to 437. Still, the wind is cross-on or onshore, so it’s marginal at best. Friday the 31st is where things start to get interesting. The mornin’ has a 6.9ft NE swell with a 9 second period, and the combined energy jumps to 1322 – that’s solid moderate energy. The wind is a light cross-on at 6 mph, which ain’t perfect but it’s workable. The score is the highest we’ve seen so far. That Friday mornin’ could be your first real chance for a session, but don’t expect perfection.

After that, the weekend of August 1st and 2nd drops back down. Saturday the 1st has a 4.3ft NE swell, but the afternoon goes glassy – light airs, wind calm. The energy is low at 155, but it’s clean. Sunday the 2nd afternoon also goes glassy with a 4.3ft swell (energy 227) and the word from the guide is “expect good surf conditions.” That might be a sneaky window for a small-wave cruise.

Then we hit the second week. Monday the 3rd and Tuesday the 4th see the swell buildin’ again. Tuesday mornin’ the 4th stands out: 6.6ft NE swell, 8 seconds, and glassy conditions with light airs. Energy is 558, and the guide says “expect very good surf conditions.” That’s a standout – clean, head-high-ish waves with no wind messin’ ’em up. Wednesday the 5th holds at 6.9ft, but the wind shifts cross-on, so it’s less ideal. Thursday the 6th and Friday the 7th keep the same pattern, with Friday afternoon seein’ a 7.9ft NE swell (energy 800) but cross-on winds pickin’ up to 9 mph, makin’ it choppy.

The real highlight, though, might be Monday the 10th of August. The mornin’ session has a 6.9ft NE swell with a 9-second period and glassy winds – energy at 655 – and the guide rates it as “expect very good surf conditions.” But the afternoon is the big talker: a 9.8ft NE swell with a 9-second period, energy roarin’ to 1156, and glassy conditions. That is *big* for this break – over 8ft, so only for experts. The guide even notes the swell might be too big for this spot. If you’re a seasoned local, that arvo session on the 10th could be the one to circle on your calendar, but it’s a long way out, so don’t lock it in just yet.

Overall, the first week is a struggle – waves are small, winds are messy, and the energy is low. The best windows are Friday mornin’ the 31st of July and Tuesday mornin’ the 4th of August for clean, solid surf. The Monday the 10th afternoon is a potential bomb, but it’s for experts only and ain’t certain this far out. Stick to the mornin’s for the cleanest conditions when you can.
